摘要

ETS transcription factors play important roles in hematopoiesis, angiogenesis, and organogenesis dur- ing murine development. The ETS genes also have a role in neoplasia, for example in Ewing's sarcomas and retrovirally induced cancers. The ETS genes encode transcription factors that bind to specific DNA sequences and activate transcription of various cellular and viral genes. To isolate novel ETS target genes, we used two approaches. In the first approach, we isolated genes by the RNA differential display technique. Previously, we have shown that the overexpression of ETS1 and ETS2 genes effects transformation of NIH 3T3 cells and specific transformants produce high levels of the ETS pro- teins.
